Flora and Vegetation: Markey and Dillon 2008 Conservation Science W. Aust. 7 (1) : 121–149 (2008) Flora and vegetation of the banded iron formations of the Yilgarn Craton: the central Tallering Land System ADRIENNE S. MARKEY AND STEVEN J. DILLON Science Division, Department of Environment and Conservation, Wildlife Research Centre, PO Box 51, Wanneroo WA 6946 Email: [email protected] ABSTRACT A quadrat-based survey was undertaken on the flora and floristic communities of several ironstone ranges and outcrops in the Yalgoo bioregion, covering the central extent of the Tallering Land System. One hundred and three 20 x 20 m quadrats were established over the extent of this region, and covered the topographic profile of these landforms. A total of 414 taxa (species, subspecies, varieties and forms) and four hybrids were identified from these quadrats. Fifteen taxa of conservation significance were found in this survey, five of which had not been previously recorded from the area. Significant range extensions for 21 species are reported in this study. At least nine new taxa were identified, of which several are of conservation significance. Nine regional endemic and near-endemic taxa were found over the study area, with half restricted to the south-west hills. Eight floristic community types (five main types, two with subtypes) were resolved from classification analysis of floristic data (presence / absence). These community types were strongly associated with topography and soil chemistry. Geographical variation was found among the floristic communities within the region, and some communities were found to be restricted to the south-west of the survey area. These restricted communities were found to occur in the more mesic regions of the survey area, on rocky uplands of BIF, and had notable component of flora from the South West Floristic Region. The central Tallering Land System is currently unreserved, although three pastoral leases have been purchased by the Western Australian Department of Conservation and Land Management (CALM) (now known as the Department of Environment and Conservation (DEC)) with the intention for future inclusion in the conservation estate. Mining and exploration tenements cover nearly all of the central Tallering Land System. This area has significant conservation values, and proposed mining activities must be assessed and managed to minimise impacts on significant flora and floristic communities.

  • Genetic Connectivity and Diversity in Inselberg Populations of Acacia Woodmaniorum, a Rare Endemic of the Yilgarn Craton Banded Iron Formations
    Heredity (2013) 111, 437–444 & 2013 Macmillan Publishers Limited All rights reserved 0018-067X/13 www.nature.com/hdy ORIGINAL ARTICLE Genetic connectivity and diversity in inselberg populations of Acacia woodmaniorum, a rare endemic of the Yilgarn Craton banded iron formations MA Millar, DJ Coates and M Byrne Historically rare plant species with disjunct population distributions and small population sizes might be expected to show significant genetic structure and low levels of genetic diversity because of the effects of inbreeding and genetic drift. Across the globe, terrestrial inselbergs are habitat for rich, often rare and endemic flora and are valuable systems for investigating evolutionary processes that shape patterns of genetic structure and levels of genetic diversity at the landscape scale. We assessed genetic structure and levels of genetic diversity across the range of the historically rare inselberg endemic Acacia woodmaniorum. Phylogeographic and genetic structure indicates that connectivity is not sufficient to produce a panmictic population across the limited geographic range of the species. However, historical levels of gene flow are sufficient to maintain a high degree of adaptive connectivity across the landscape. Genetic diversity indicates gene flow is sufficient to largely counteract any negative genetic effects of inbreeding and random genetic drift in even the most disjunct or smallest populations. Phylogeographic and genetic structure, a signal of isolation by distance and a lack of evidence of recent genetic bottlenecks suggest long-term stability of contemporary population distributions and population sizes. There is some evidence that genetic connectivity among disjunct outcrops may be facilitated by the occasional long distance dispersal of Acacia polyads carried by insect pollinators moved by prevailing winds.

The weather may have been hot and dry, but that didn’t stop everyone having fun and learning about the rich biodiversity and conservation value of the wonderful Canna Reserve during the highly successful 2019 BioBlitz. On the 14 - 15 September 2019, NACC NRM together with support from Department of Biodiversity Conservation and Attractions and the Shire of Morawa, hosted their third BioBlitz at the Canna Reserve in the Shire of Morawa. Fifty professional biologists and citizen scientists attended the event with people travelling from near and far including Morawa, Perenjori, Geraldton and Perth. After an introduction and Acknowledgement of Country from organisers Jessica Stingemore and Jarna Kendle, the BioBlitz kicked off with participants separating into four teams and heading out to explore Canna Reserve with the goal of identifying as many plants, birds, invertebrates, and vertebrates as possible in a 24 hr period. David Knowles of Spineless Wonders led the invertebrate survey with assistance from, OAM recipient Allen Sundholm, Jenny Borger of Jenny Borger Botanical Consultancy led the plant team, BirdLife Midwest member Alice Bishop guided the bird survey team and David Pongracz from Department of Biodiversity Conservation and Attractions ran the vertebrate surveys with assistance from volunteer Corin Desmond. The BioBlitz got off to a great start identifying 80 plant species during the first survey with many more species to come and even a new orchid find for the reserve.

    DRAFT 25/10/90; plant list updated Oct. 1992; notes added June 2021. PRELIMINARY REPORT ON THE CONSERVATION VALUES OF OPEN COUNTRY PADDOCK, BOOLARDY STATION Allan H. Burbidge and J.K. Rolfe INTRODUCTION Boolardy Station is situated about 150 km north of Yalgoo and 140 km west-north-west of Cue, in the Shire of Murchison, Western Australia. Open Country Paddock (about 16 000 ha) is in the south-east corner of the station, at 27o05'S, 116o50'E. The most prominent named feature is Coolamooka Hill, near the eastern boundary of the paddock. There are no conservation reserves in this region, although there are some small reserves set aside for various other purposes. Previous biological data for the station consist of broad scale vegetation mapping and land system mapping. Beard (1976) mapped the entire Murchison region at 1: 1 000 000. The Open Country Paddock area was mapped as supporting mulga woodlands and shrublands. More detailed mapping of land system units for rangeland assessment purposes has been carried out more recently at a scale of 1: 40 000 (Payne and Curry in prep.). Seven land systems were identified in open Country Paddock (Fig. 1). Apart from these studies, no detailed biological survey work appears to have been done in the area. Open Country Paddock has been only lightly grazed by domestic stock because of the presence of Kite-leaf Poison (Gastrolobium laytonii) and a lack of fresh water. Because of this and the generally good condition of the paddock and presence of a wide range of plant species, P.J.

Aust. 7 (1) : 153–178 (2008) Flora and Vegetation of the banded iron formations of the Yilgarn Craton: the Weld Range ADRIENNE S MARKEY AND STEVEN J DILLON Science Division, Department of Environment and Conservation, Wildlife Research Centre, PO Box 51, Wanneroo WA 6946. Email: [email protected] ABSTRACT A survey of the flora and floristic communities of the Weld Range, in the Murchison region of Western Australia, was undertaken using classification and ordination analysis of quadrat data. A total of 239 taxa (species, subspecies and varieties) and five hybrids of vascular plants were collected and identified from within the survey area. Of these, 229 taxa were native and 10 species were introduced. Eight priority species were located in this survey, six of these being new records for the Weld Range. Although no species endemic to the Weld Range were located in this survey, new populations of three priority listed taxa were identified which represent significant range extensions for these taxa of conservation significance. Eight floristic community types (six types, two of these subdivided into two subtypes each) were identified and described for the Weld Range, with the primary division in the classification separating a dolerite-associated floristic community from those on banded iron formation. Floristic communities occurring on BIF were found to be associated with topographic relief, underlying geology and soil chemistry. There did not appear to be any restricted communities within the landform, but some communities may be geographically restricted to the Weld Range. Because these communities on the Weld Range are so closely associated with topography and substrate, they are vulnerable to impact from mineral exploration and open cast mining.

  • (Centrolepidaceae) in Australia
    J. Adelaide Bot. Gard. 15(1): 1-63 (1992) A TAXONOMIC REVISION OF CENTROLEPIS (CENTROLEPIDACEAE) IN AUSTRALIA D. A. Cooke Animal and Plant Control Commission of South Australia GPO Box 1671, Adelaide, South Australia 5001 Abstract Centrdepis in Australia is revised and twenty species are recognised. This revision is based on morphological features that are discussed in relation to the biology of the genus. One new species, C. curta, and a new subspecies, C. strigosa subsp. rupestris, are described and illustrated. The new combinations C. monogyna subsp. paludicola and C. strigosa subsp. pulvinata are made. Introduction Centrolepis is a genus of small annual and perennial monocots. It forms, with Aphelia and Gaimardia, the minor family Centrolepidaceae. The family has its main centre of diversity in Australia with 29 species; a few occur in New Zealand, south-eastern Asia and South America. The close affinity of the Centrolepidaceae to the Restionaceae, and its remoteness from the two genera segregated by Hamann (1976) as the Hydatellaceae, are widely recognised in contemporary systems of classification (Cronquist, 1981; Dahlgren & Clifford, 1982; Takhtajan, 1980). Taxonomic history The genus first became known from material of the near-coastal species sent to Europe by the early botanist-explorers and collectors. In 1770 Banks and Solander on the Endeavour collected specimens of Centrolepis, now referred to C. banksii and C. exserta, that they tentatively labelled as species of Schoenus (Cyperaceae). Labillardière (1804) based the new genus Centrolepis, which he placed under Monandria Monogynia in the Linnaean system, on a Tasmanian specimen. Robert Brown (1810), using Banks' and Solander's material and his own collections from the voyage of the Investigator around Australia in 1801-4, drafted manuscript epithets for a further twelve Centrolepis species.
